Hello As far as I know, there is no support for that, if you are using Apache you can delegate the authentication to it: * Add the LDAP and Kerberos modules to Apache and configure them. * Set an env variable so PHP can have access to the authenticated user. Maybe this example can help you: https://danieljamesscott.org/all-articles/10-articles/configuration-guides/9-apache-kerberos-and-ldap-integration.html -----Original Message----- From: michael@xxxxxxxxxxxxx <michael@xxxxxxxxxxxxx> Sent: jueves, 24 de octubre de 2019 07:55 a. m. To: php-general@xxxxxxxxxxxxx Subject: LDAP SASL GSSAPI Hi! I want to bind to ldap using a kerberos ticket. Here is my code: putenv( 'KRB5CCNAME=' . $_SERVER['KRB5CCNAME'] ); $ldapConnection = ldap_connect( 'ldap://dc.contoso.com' ); $bind = ldap_sasl_bind( $ldapConnection, NULL, NULL, 'GSSAPI' ); var_dump( error_get_last( ) ); I get a "ldap_sasl_bind(): Unable to bind to server: Not Supported" Error. ldap_search using SASL on the Command Line (ldapsearch -Hldap://dc.constoso.com -bdc=dc,dc=contoso,dc=com samaccountname=user1) works fine. Do you guys have any pointers on how to get that working? Thanks, Mike
